German term

Abblendlichtgeometrie

German to English Tech/Engineering Transport / Transportation / Shipping Electric Locomotive
"Für die Funktion „Scheinwerfer abgeblendet“ kommen Linsenscheinwerfer zum Einsatz, deren exakte Abblendlichtgeometrie ein Blenden des Gegenverkehrs auch bei Gleiswechselbetrieb ausschließt."

From a text about a type of electric locomotive. This bit is talking about the exterior lights. I can't make head or tail of "Abblendlichtgeometrie" and can find no references to it anywhere. TIA for any light you can shed (no pun intended - honest!) on this extremely obscure word.

Low-beam geometry??? Gets no Google hits, but then neither does Abblendlichtgeometrie ...

low-beam light distribution pattern (...light arrangement)

or: low-beam light (lamp) geometry (design - if for housing)

http://www.eurodezigns.com/Led Brake Lightso.html
All low (passing, lower, dipped) beams are an asymmetrical distribution of light to give maximum seeing in the direction of travel while controlling glare light directed towards oncoming traffic.

Depending upon the geometry of the particular embodiment, the beam of light 53 may be collinear with or may be parallel to the central line of the flow of rail conditioning material 45.

The FRA requires that the headlight luminous intensity for locomotives used in yard service be 60,000 candela; the light must be arranged to illuminate a person at least 91.5 m (300 ft) ahead and in front of the headlight. The railroad industry operates road locomotives and yard locomotives with the headlight continuously turned on. The FRA requires a dimmer switch; this is used to operate the headlight at low beam at night and when passing oncoming locomotives.


The standard locomotive headlight is aimed down the track center-line and has a narrow, horizontal 3.5° beam width, as shown in Figure 3-2.

low beam lens pattern

I'd call it "geometrically precise low beam lens pattern".

By posting it here, it should from now on be appear on Google as well :)

Please ignore the "on be" - don't know what it's doing there.

low-beam configuration/setting


You are in fact correct in translating it as "low-beam geometry" - by geometry they mean configuration/design of its low-beam setting. The only thing is it might give rise to ambiguity, since it's unheard of (and since the first thing that comes to mind with 'geometry' is the branch of math.)
